Structure-based design, synthesis, and biological evaluation of a series of dihydroquinazoline-derived β-secretaseinhibitors incorporating thiazole and pyrazole-derived P2-ligands are described. We have identified inhibitor 4f which has shown potent enzyme inhibitory (Ki = 13 nM) and cellular (IC50 = 21 nM in neuroblastoma cells) assays. A model of 4f was created based upon the X-ray structure of
描述了一系列包含噻唑和吡唑衍生 P2-配体的二氢喹唑啉衍生 β-分泌酶抑制剂的基于结构的设计、合成和生物学评价。我们已鉴定出抑制剂4f,其在酶抑制 (K i = 13 nM) 和细胞 (IC 50 = 21 nM 在神经母细胞瘤细胞中) 测定中表现出强效。基于3a结合 β-分泌酶的 X 射线结构创建了4f模型。该模型建议了活性位点中可能的相互作用。
